The purpose of this article is to review the early complications of minimally invasive mobile-bearing unicompartmental knee arthroplasty by analyzing the first 100 consecutive cases. All cases were medial unicompartmental arthroplasties with a follow-up of at least 24 months (range, 24-51 months). Seven revision procedures were performed due to 2 fractures of the medial tibial plateau, 1 loosening of the femoral component, and 4 dislocations of the meniscal bearing. The early results as determined by The Knee Society scores, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores and postoperative range of motion were satisfactory. However, there exists a high rate of early failures, which occurred during the initial learning curve. Therefore, surgeons must be aware that in order to minimize these complications, attention to detail is mandatory.
本文旨在通过分析前 100 例连续病例，回顾微创活动平台单髁膝关节置换术的早期并发症。所有病例均为内侧单髁关节置换术，随访时间至少 24 个月（范围：24-51 个月）。7 例患者因内侧胫骨平台骨折、1 例股骨组件松动和 4 例半月板轴承脱位而进行了翻修手术。膝关节学会评分、安大略西部和麦克马斯特大学骨关节炎指数（WOMAC）评分和术后活动范围的早期结果令人满意。然而，存在较高的早期失败率，这些失败发生在初始学习曲线期间。因此，外科医生必须意识到，为了尽量减少这些并发症，必须注意细节。
